IMPROVEMENT IN WASH-BOILER FOUNTAINS.

Specification forming partof Letters Patent No. 222.442, dated December 9, 1879; application filed August 15, 1879.

To all whom it may concern; I

Be it known that 1, WILLIAM BARTON, of

Newark, Essex county, New Jersey, have invented certain new and useful Improvements in Wash-Boiler Fountains, of which the following 1s a specification.

My invention relates to those attachments for boilers which usually consist of a hollow base, with a tube rising therefrom and curving downward at its top, and which, when placed in an ordinary wash-boiler with the hollowbase resting on the heated bottom f thereof, produce, by the ebullition of the water in the hollow base, a continuous flow of steam and water from the mouth of the tube over the top of the clothes in the boiler.

My invention aims to provide a device of this kind which will be certain and effective in its action and capable of discharging a large volume of water; and my invention is embodied in an air and steam chamber, in

. combination with and rising out of the hollow base, and in the special form of the water-passages in the base, as hereinafter set forth.

\ In the, annexed drawings, Figure 1 presents a side elevation of my improved wash-boiler fountain, and Fig. 2 an inverted. plan thereof.

In the illustration, a indicates the hollow base of the fountain, and b the discharge-tube rising therefrom in about the usual manner.

The base is preferably of circular form, as usual, and the discharge-tube extends from the top at or near its center.

The bottom of the base is open in the usual I manner, and is adapted to rest on the bottom of the wash-boiler, and its interior is formed with spiral passages verging to the center of the base, to which the cooler water of the boiler is admitted through a peripheral openand, furthermore, the passages are formed "than a passage of uniform width or direction for producing an energetic flow of the water toward the central discharge, and it renders the flow more certain and voluminous and of a more pulsating character, and constitutes one feature of my invention.

Another feature of my invention lies in the dome d or steam and vacuum chamber, which rises out of the top of the base a close-to the outlet 1), and opens in the interior of the base into a small isolated or partitioned chamber, 6. The addition of this feature is found to cause the fountain to start into action sooner, and to render the flow larger and more steady than would be the case were this feature omitted. I have not yet arrived at a satisfactory theory of its operation; but practically it appears to serve partly as an elastic reservoir, to prevent sudden or violent spurting of the foaming water from the discharge-tube, and also acts as a pulsating vacuum-pump.

With these combined features of construction the device is found to discharge a much larger stream than with the ordinary construction, and the stream is of a uniform pulsatin g character, and produces a slight pulsation in the mass of the clothes, which greatly- "assists in washing out the dirt therefrom.

' I prefer to form the base a with its partitions by casting it in one piece, as illustrated, and subsequently galvanizing it, short necks being cast on its upper side to receive the discharge-tube 1), preferably made of sheet-tin,

and also to receive the neck of the dome d, which is preferably spun into shape from sheet metal, but may be cast solidly on the base.

I am aware that it is common to use spiral passages in the base of boiler-foul'itains, and sometimes spiral passages laterally serrated or scalloped, and hence disclaim the same.

What I claim as my invention is a hollow base provided with the dome or 0112111 1. A wash-boiler fountain constructed with her d, rising out of the top thereof, substana hollow base formed. with zigzag or altertially as herein shown and. described.
